Solve 2(x+7)^2=56
\n" ); document.write( "(x+7)^2=56/2=28
\n" ); document.write( "take sqrt of both sides
\n" ); document.write( "x+7=±√28
\n" ); document.write( "x=-7±√28
\n" ); document.write( "x=-7+√28=-1.71
\n" ); document.write( "or
\n" ); document.write( "x=-7-√28=-12.29 \n" ); document.write( "
\n" );
